Most of those are pretty evidently distinguishable from real life... The issue here - and the point being made - is that we are already at the stage where many CG images can fool even close observers, and we've been here for some time. We've been passing around these "CGI OR REAL?!!!!" images for a few years at least, and when they are first created people really can't tell the difference, but yet somehow when people get used to the tech and revisit these images a few years down the line they look obviously synthesized. Ditto older movies like Jurassic Park, whose cutting edge CGI of the time were convincing even when viewing frame-by-frame, but to savvy eyes appears downright obvious today. So clearly "photoreal" is something we haven't reached yet. IMO the indicator that we've reached "true photoreal" is when an image rendered 5 years ago still holds up to fresh eyes.
